Yeah, I definitely wouldn't taken it as a major condemnation, he's 18 and 19 games into his career playing against men. Just haven't seen much of an offensive game from him. The fact they rely on him so much over there is a good sign he's gonna be a player.
I’ve watched the majority of his games this season and I disagree with your assessment of him being “sloppy” with the puck. In fact, I think he’s been the opposite.
He may not possess an impressive offsensive-skill set, but that’s not what he was drafted for, nor has it ever been his game.
SaiPa employs his services in just about every situation you can think of, and for good reason. He’s one of the best skaters you’ll find, and has a great set of defensive tools that he knows his limits with. He has been making safe plays, and on top of it, can really connect a great first-pass out of the zone. He’s a really good puck-moving defender.
Vaakanainen has been logging some heavy minutes, too. He currently ranks 10th in the entire Liiga for TOI, as well.
His gap-control and defensive-stick is exceptional, he rarely lets a player beat him to the inside of the ice. He can jump on pucks quickly down low and then skate himself out of trouble.
As a potential defensive partner to McAvoy one day, he could very well end up mimicking what Seidenberg was able to offer Chara for all those years.
